Npoi导出word(Peanuts)

一个项目，要做一个从数据库读取数据，然后导出到word，因为涉及到后台数据库的读取，决定用npoi来导出word。

NPOI源码地址：http://npoi.codeplex.com/

NPOI 2.0 api文档： http://www.npoi.info/npoi2tutorial
因为npoi操作word的文章比较少，在由于版本不同，相关的函数可能不一样，这个就需要大家自己去慢慢的探索了。

例如：作者的api文档中

c.字体加粗

r1.SetBold(true);

实际我在调用时，调用的接口是 r1c1.IsBold = 12;

我使用的版本是：NPOI v2.2.0.0

需要引用的命名空间如下

using NPOI.XWPF.UserModel;

using NPOI.OpenXmlFormats.Wordprocessing;

最终效果图如下：



关键代码如下：

/// <summary>
/// 新增
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void btnPrint_Click(object sender, EventArgs e)
{
//创建document对象
XWPFDocument doc = new XWPFDocument();
//创建段落对象
XWPFParagraph p1 = doc.CreateParagraph();
p1.Alignment = ParagraphAlignment.CENTER;//字体居中
//创建run对象
//本节提到的所有样式都是基于XWPFRun的，
//你可以把XWPFRun理解成一小段文字的描述对象，
//这也是Word文档的特征，即文本描述性文档。
//来自Tony Qu http://tonyqus.sinaapp.com/archives/609 XWPFRun runTitle = p1.CreateRun();
runTitle.IsBold = true;
runTitle.SetText("军检验收单");
runTitle.FontSize = 16;
runTitle.SetFontFamily("宋体", FontCharRange.None);//设置雅黑字体

XWPFParagraph p2 = doc.CreateParagraph();
XWPFRun run1 = p2.CreateRun();
run1.SetText(" 军检项目号：");
run1.FontSize = 12;
run1.SetFontFamily("华文楷体", FontCharRange.None);//设置雅黑字体

设置table的宽度，以及没列的宽度代码如下：

XWPFTable tableTop = doc.CreateTable(6, 5);
tableTop.Width = 1000 * 5;/* 设置table宽度，必须设置width，SetColumnWidth才有效 */
tableTop.SetColumnWidth(0, 1300);/* 设置第一列宽 */
tableTop.SetColumnWidth(1, 500);/* 设置第二列宽 */
tableTop.SetColumnWidth(2, 1000);/* 设置列宽 */
tableTop.SetColumnWidth(3, 500);/* 设置列宽 */
tableTop.SetColumnWidth(4, 1700);/* 设置列宽 */

和并列以及设置列的高度：
tableTop.GetRow(0).MergeCells(1, 4);/* 合并列 */

XWPFRun r1c1 = pCell.CreateRun();

r1c1.SetText(setText);

r1c1.FontSize = 12;

r1c1.SetFontFamily("华文楷体", FontCharRange.None);//设置雅黑字体

r1c1.SetTextPosition(textPos);//设置高度
